Project Entropy contracts

Stories in Ready Build Status

Entropy is an Ethereum-powered floating experiment

We're establishing a crowd-owned and community steered fleet of sailing hackspaces around the world.

This repository is a collection of Solidity scripts, used to create the Smart Contracts running on Ethereum which form the core of Project Entropy: it's governence model, citizenship and logic of operations.

We use Truffle as a contract development framework.

Throughput Graph


Entropy is built with an experimental but simple DAO structure designed to balance a real world project with the benefits of crowd wisdom and blockchain transparency.

Community 🏡

Citizens 👬 hold the following rights:

  • A single Vote on every created Action 💡
  • Creating Actions 💡
  • Guardian 💂‍♂️ nomination

Anyone can become a Citizen 🏃 by obtaining and holding one or more Entropy Tokens 🍪

The individuality of citizens is confirmed by the guardians, once it is confirmed they become Trusted Citizens 👭

Trusted Citizens 👭 hold equal voting rights to all trusted individuals in the Entropy Community, they are able to suggest any Action 💡 for discussion and vote. These Actions 💡 can be anything at all, from destinations to sail to, events, changes to the mission itself and changes to the Guardians 💂‍♂️

Guardians 💂‍♂️

Guardians 💂‍♂️ take on the responsibility to fulfil and document everything within the Action Stream 📋 as organised by and voted on by the wider community.

They have, in addition to the rights of all Citizens 🏃, access to any shared funds moved to the Slush Pool 💰 by the community voting as a whole.

Guardians are also able to mark Citizens as trusted, allowing for a human-based proof of individuality system.

Any Citizen 🏃 can be elected to be a Guardian 💂‍♂️ by an accepted Action 💡

Guardians are accountable to the wider community and can, if needs be, be unelected by a successful Action against them.

Actions and Funds 💡 💰

Any Citizen 🏃 can propose a new Action 💡

All Actions 💡 can be voted on by the entire community for 5 days.

For an Action 💡 to be accepted, it must have more than 50% approval and at least as many votes as there are Guardian 💂‍♂️ members (although voting is open to all Citizens 👪).

After this period accepted Actions 💡 will be added to the Action Stream 📋 until they are marked as complete by one of the Guardians 💂‍♂️

Declined Actions 💡 will be dismissed to the Archive ♻️

The Action Stream 📋 represents what the community is currently aiming to achieve.

Any funds associated with Actions 💡 in the Action Stream 📋 become available in the Slush Pool 💰 for the Guardians 💂‍♂️ to use towards making those Actions 💡 happen.

The recommended workflow for developing and contributing to the contracts is using the truffle console for compiling, deploying and playing with contracts. In order to do that, just:

$ npm install -g truffle ethereumjs-testrpc

$ testrpc // leave process running
$ truffle console
> compile
Compiling Entropy.sol
> migrate --reset
> var entropy = Entropy.deployed()
Instance of an eth-pudding object to interactive with the live Entropy instance

You need to be running a Ethereum node with RPC enabled for Truffle to connect. In this example, we are just running it with testrpc, which is a in-memory RPC enabled node written in JS, that is very fast for development and testing. This can be run also on a private blockchain running with geth, the Ethereum testnet or the mainnet. See Truffle network configuration for more info.

To run the EntropyTestnet and connect to it with something expecting geth, run:

$ parity --chain ./entropy_testnet_chainspec.json --geth


Uncaught BigNumber Error: new BigNumber() not a base 16 number:

This can mean a string you were trying to access is null.


To run the tests, spin up an ethereum node and run:

$ truffle test

For running in the CI, a Docker image has been created for the sake of simplicity. It starts a testrpc node and runs the tests against it.
